The correct answer is A) A roast at 125°F (52°C)
Explanation:
In general terms, bacteria thrive at warm temperatures; this means bacterial growth is lower at extremely hot/cold temperatures, but it is higher at warm or medium temperatures. Indeed, the ideal temperature for bacteria to develop and reproduce is between 4° C and 60°C. This implies from the options given the roast at 52°C represents an ideal temperature for the growth of bacteria. Also, other options include temperatures above 60°C, and therefore do not allow bacteria to grow well.
B is the answer to your question.

Answer : True
Enrichment cultures are used to increase a small number of desired organisms
The term 2pq represented in the hardy-weinberg equation is the frequency of heterozygotes and is denoted as option D.
<h3>What is Hardy-weinberg equation?</h3>
This mathematical equation is used to calculate the genetic variation of a population at equilibrium and can be seen below:
p² + 2pq + q² = 1
where
p² is dominant homozygous frequency (AA)
2pq is heterozygous frequency (Aa)
q² is recessive homozygous frequency (aa).
The 2pq can be seen as the heterozygous frequency which is therefore the reason why option D which is frequency of heterozygotes was chosen as the most appropriate choice.
